Method for determining the condition of engine oil based on soot modeling |
摘要 |
A method for monitoring the condition of oil in an engine is disclosed which includes the steps of determining a plurality of parameters, determining a fuel injection model, determining the area of the cylinder walls that is coated with soot, and responsively determining a soot model. The method may include the additional steps of calculating a value of residual soot, and calculating a value of soot dispersed by dispersants. The accumulation of soot determined from the model may be trended over time to predict the useful life of the oil.
